AIM Sports Tactical Shotgun Quad Rail - Manual (Page 2)

Step 1: Locate barrel/magazine tube clamp and two 1 11/64”
screws. Assemble clamp using the two beveled holes finger
tight only. Note that the openings are different sizes and
shapes. The smaller sized opening attaches to the barrel, and
the larger opening attaches to the magazine tube.
Step 2: Disassemble the clamp and assemble it onto the
barrel/magazine tube in the same position pictured on left.
Do not tighten the screws down all the way as you will need

trigger assembly pins by using a pin punch. Leave the trigger
assembly in place.
Step 4: Slide the battle rail over the barrel and position
it over the receiver.
Step 5: Insert the plastic spacers provided on both sides
of the receiver. Align the holes in the spacers with the
trigger pin holes in the receiver with a punch or drift pin.
Step 6: Insert the new provided trigger pins into the
appropriate sized trigger pin hole, using a rubber
mallet if needed.
Step 7: Insert the provided 23/64” allen screw into
each end of the trigger pins and tighten with the

magazine clamp, and install 1” screw and tighten.
